Further to my earlier post regarding Coolports. I have checked with my
friend, and found that the Telephone Handsets aren't digital phones,
but VOIP handsets.

Am I right in thinking that in terms of cabling these are just Ethernet
Twisted Pair devices which usthe same two pairs as 10 Base T or 100
Base T and could therefore be expected to work with the 2 x Data type
Coolports (Or more to the point the cheaper (though less sexy) port
economisers which Videk and others stock)?

I can probably get away with just using these devices on the computer
connections (where I know there will be no problems), but it would be
interesting to know if they could also be used with the VOIP kit.
